Makeshift supports. Makeshift supports are never quite right for the job. And they're not safe. For instance, don't stand on top of a trash can or chair instead of a stepstool or ladder. This raises your risk of falling and hurting yourself. Never make a short ladder taller by putting something under the legs. And be careful not to overreach. This can shift your center of gravity and make you lose your balance.

Incorrect use of ladders. Using equipment incorrectly is a common fall hazard. If you set a ladder too close or too far from a building, you're more likely to fall off of it. Other causes of falls include setting the ladder on loose, uneven ground. Or using a tall ladder by yourself without securing it. And never stand on the top of a stepladder or use an extension ladder that's too short.

Find out what you need ahead of time.

Follow safety warnings on equipment.

Keep yourself centered over your support so you're less likely to lose your balance.

Keep your arms and legs as close to your center of gravity as possible (don't overreach).

Inspect the ladder before using it.

Use the 1 to 4 rule. The base of the ladder needs to be placed 1 foot out from its support for every 4 feet of ladder length.

Set and secure the ladder on stable ground.

Have someone hold the base of the ladder.

Never use the top rung.
